MORTIMER B. MILLS AND CHARLES B. RICE, OF CHICAGO, ILLINOIS; SAID MILLS ASSIGNOR TO SAID RICE.

FEED-COOKER.

SPECIFICATION forming part of Letters Patent No. 232,101, dated September 7, 1880.

Application filed March 22, 1880. (No model.)

To all whom it may concern:

Be it known that we, MORTIMER B. MILLS and CHARLES B. RICE, both of Chicago, Illi nois, have invented a new and useful Improvement in Fced-Oookers,which is fully described in the following specification, reference being had to the accompanying drawings, in which Figure 1 represents a vertical section of our improved feed-cooker; and Pi g. 2, a horizontal [0 section taken on the line a: 01, Fig. 1.

Our invention is an improvement in the class of steam-generating apparatus for use in cooking feed for live stock.

We aim to provide an apparatus which shall be compact in form, adapted for heating the water quickly, and provided with means for automatically regulating the supply of water, the latter, when admitted, being discharged downward in to the lower chamber of the boiler,

where the highest. degree of heat is available.

The details of construction and arrangement: of parts are as hereinafter described and claimed.

In the drawings, A represents a steam-chest with holes at the bottom to receive the pipes O, which are made watertight. The lower ends of the pipes G are screwed into a hollow cast-iron cylinder, B, the center of which is made so as to receive a grate, G. At the bot- 0 tom of the cylinder B and under the grate G is an ash-pan, I*, and there are legs P attached to the bottom of the cylinder B.

A drum or jacket, E, surrounds the pipes C, so as to retain the tire and smoke.

5 D is the smoke-pipe, and O the door for putting in the fuel.

H represents a copper ball, which is hollow and connected to the water-cock I, so as to shut off the opening in the latter when the water rises above the high-water mark.

K is a pipe to be attached to the water-reservoir to supply the boiler when necessary.

L is a pipe to be connected to the top of the reservoir to supply the latter with steam-pressure to counterbalance the pressure in the boiler. 4 5

The steam-pipe M conducts the steam to the feed to be cooked.

N is a safety-valve.

We do not claim, broadly, the automatic regulation of the supply of water to a boiler-5o by means of a float and lever connected with acock in the waterinlet pipe.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. The improved steamer for use in cooking food for live stock, the same consisting of the water-chambers A B, pipes G, connecting the same and arranged in a circle, the surrounding casing E, water induction, steam, and 6c smoke pipes, attached as specified, and the water-supply-regulating device, consisting of the lever, float, and cook in pipe K, inclosed in the chamber A, all as shown and described.

2. In a steamer for use in cooking food for 5 live stock, the combination, with the upper and lower water chambers, A B, and vertical connecting-pipes G, of the water-supply pipe K, which passes through the upper chamber and enters one of said pipes G, as shown and 7 described.
